Inventor: PRUCKMAYR GERFRIED
IPC: C08G65/20
Filed: 1985-06-03
Abstract: In the preparation of poly(tetramethylene ether) glycol by the polymerization of tetrahydrofuran (THF) using a cationic initiator, molecular weight distribution (MWD) can be held within narrow limits by bringing the THF and the initiator together in a mol ratio such that the degree of polymerization will be at about a minimum and at a temperature which will promote about a maximum number of tertiary oxonium ions, then quickly cooling the reaction mass to -25°C to +25°C, and then adding enough THF to complete the polymerization. When the desired molecular weight and MWD have been reached, the polymerization is quenched and the polymer isolated.

Abstract: 1. Process for the production of carbon dioxide and ethanol by continuous fermentation of a culture medium inoculated with micro-organisms of the bacterial type appertaining to the flocculant Zymomonas genus with retention and recycling of the micro-organisms, the retention being effected by internal decanting and recycling obtained by a reduction of the speed of circulation of the fluids, with reduction of the turbulence in the upper part of the fermentation zone by a sudden enlargement of the cross-section of the said zone, characterized in that the culture medium is inoculated with a highly flocculant strain of Zymomonas mobilis, deposited at the pasteur Institute under the number I-411, and in that the fermentation gases are collected at the centre of the upper part of the fermenting zone where the turbulence of the fermentation medium is reduced, with collection and withdrawal of the carbon dioxide produced at different levels of the fermentation zone.

Abstract: Polyamines containing primary amino groups are prepared in a single stage process by hydrolyzing an isocyanate in the presence of a catalyst incorporable through an NCO reactive group and a water-miscible aprotic-dipolar solvent. This hydrolysis is carried out at from 20 DEG  to 210 DEG  C. with the reactants being in substantially homogeneous phase. The isocyanate starting material has an NCO content of from 0.5 to 40% by weight. The catalyst is used in a quantity of at least 0.0001% by weight, based on 100% by weight of isocyanate compound. The water-miscible solvent is used in a quantity of at least 10% by weight, based on 100% by weight of isocyanate compound. The polyamines thus produced are particularly useful in the production of polyurethanes.

Abstract: Method and means for treating of and mass transfer in liquid/gas mixtures, especially removal of oxygen from seawater to be injected into deep structures to increase the production of underground hydrocarbon resources. The oxygen removal is performed by means of an inert stripping gas which is purified and regenerated before it is recirculated. 
<??>Liquid and gas is pumped in turbulent concurrent flow with the inert gas through one or more tubelike zones (2) to one or more separation zones (6) where gas and liquid are separated. The liquid is led to the next treatment stage, while the stripping gas is returned to the prior treatment stage. The liquid flow and the gas flow are pumped and controlled independently of each other, to allow optimal treatment conditions and correct amount of transported liquid to be obtained.

Abstract: The spirit of the invention is a rotary-head wet shaver with a shaving head 2 which has single or double razor blades 7 and which is arranged at the front end of a handle 1, a plurality of razor blades 7 being arranged on a common blade carrier 6, rotatable about an axis A, uniformly over the circumference of the latter. The cutting edges 8 of the razor blades 7 extend parallel to this axis A, and the blade carrier 6 together with the razor blades 7 can be rotated by means of a rotary knob 11 lying in the axis A and located on the blade carrier 6, into the respective shaving position and be locked there. To improve the handling of the shaver, it is proposed that it be possible for the rotary knob 11 to be pulled out. It is proposed, furthermore, that the blade carrier 6 be attachable on to the free end of a rotary axle 4, whilst the blade carrier 6 can additionally be equipped with a cover cap 16 and with a wire coil. This wire coil can likewise be used for all conventional razor blades and is not restricted to those blade carriers on rotary-head shavers.

Abstract: A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems. The suspend/resume/standby feature is implemented at a low cost using many standard components. <IMAGE>
